Founder: Orhan

Orhan Bey continues his nine-year siege of Bursa to fulfill Osman Bey’s vision, facing formidable resistance from Saroz and Flavius. As tensions rise, Osman Bey convenes a council that could decide Bursa’s fate, with Şahinşah Bey challenging Orhan’s command and Alaeddin Bey offering himself as an alternative. Amid political turmoil, Nilüfer Hatun stands by Orhan with unwavering support, while Malhun Hatun, losing hope in Gonca, seeks a new bride for Alaeddin. Orhan escalates the conflict by killing Flavius’s brother, prompting a vow of revenge and setting the stage for a storm at Bursa’s gates.

Orhan Bey returns victorious but is shaken by unexpected news, prompting him to surrender his position to Osman Bey with a solemn acceptance of fate. As tensions rise between Alaeddin and Orhan, Temurtaş's secretive alliance with Saroz and his hosting of Şahinşah and Alaeddin deepen the intrigue, especially as his schemes leave Osman Bey bedridden. Orhan faces mounting pressure from Byzantine and Ilkhanate forces while striving to fulfill his father's dream of conquering Bursa, where he confronts the vengeful Flavius in a deadly bid to rescue Boran. Meanwhile, Temurtash Noyan’s arrival threatens to upend the regional balance of power. Nilüfer Hatun’s belief that Orhan has been wronged sparks conflict among the women, potentially pitting her against Gonca and drawing a decisive response from Malhun Hatun. In a final blow, Osman Bey reclaims command of the siege and appoints Şahinşah Bey as leader, sidelining Orhan once more.

As the Byzantine, Ilkhanate, and Turkmen forces unite to defend Bursa, Orhan Bey urges diplomacy to dismantle the alliance, clashing with Şahinşah’s call for immediate attack despite Osman Bey’s illness. Tensions rise in the council and within the family, as Malhun Hatun fears division among her children, especially with Gonca believing Alaeddin deserves leadership while Didar claims Malhun favors Orhan. Meanwhile, enemies Temurtash, Saroz, and Flavius plot a devastating strike on the Kayı tribe, targeting a caravan led by Fatma Hatun. Driven by vengeance, Flavius seeks to capture her, but Orhan Bey confronts him head-on, determined to fulfill a hidden purpose in their fierce showdown.

Orhan Bey faces a critical test of leadership as tensions rise within the Kayı tribe, challenged by both his father and brother to prevent internal division. Supported by Nilüfer Hatun, he survives an ambush with help from Kan Turalı and Abdurrahman, then seeks to lift the siege of Bursa by negotiating with Temurtaş, risking confrontation with Alaeddin and Şahinşah Bey. Meanwhile, Flavius plots revenge in Söğüt, torn between attacking and protecting Fatma Hatun. Temurtaş’s brutal raid on Yarhisar leaves the tribe mourning, prompting Malhun Hatun to confront Alaeddin Bey. Despite Orhan’s efforts to stop the war, Alaeddin orders him to Karacahisar; when Orhan refuses, their conflict erupts into violence, leading to Orhan’s exile and a deep fracture in the tribe’s unity.

As Orhan Bey assumes leadership, unrest brews when Şahinşah Bey, angered by his removal from command despite pledging allegiance, seeks to challenge him. Determined to prove himself, Orhan Bey plans with Abdurrahman and Kanturalı to retake Yarhisar and honor fallen martyrs, marking his first true test. Meanwhile, Flavius, thwarted by the destruction of the Bursa tunnel, turns to violence, plotting an assassination against Osman Bey during Orhan’s sword-girding ceremony. With obstacles cleared in the camp, Orhan Bey advances his ambitions, seizing Bursa and issuing his first threat to Iznik, setting the stage for a new era defined by his uncompromising stance against the Tekfur.

Orhan Bey’s campaign to win Bursa blends mercy and strategy, alarming the Byzantines while a hidden threat rises in Söğüt. Flavius entangles Fatma in his schemes, suitors stir tensions in the camp, and Şahinşah’s loyalty is questioned as Temurtaş is courted. The Emperor’s sudden arrival with a mysterious woman promises to upend the tribe’s balance of power.
